What does Interview Solver do?

Interview Solver is a specialized desktop application designed to function as an invisible AI copilot during live coding interviews. Its core function is to provide real-time solutions to LeetCode problems and system design questions directly within your interview environment. The tool captures problems via screengrabs or live audio transcription and instantly delivers answers, explanations, and code, all while remaining hidden from the interviewer's view during screen sharing. It's built for the high-pressure, high-stakes scenario of a technical interview.

What makes Interview Solver stand out is its intense focus on stealth and seamless integration. Unlike browser extensions that can be flagged, it's a native desktop app with features like an invisible overlay, global hotkeys that bypass browser detection, and support for transparency so you can glance at solutions without looking away. It's trained on the entire LeetCode dataset and can generate solutions with syntax highlighting and flowcharts. The tool is built to work with major platforms like Zoom, Teams, and Google Meet, specifically engineered to be undetectable in proctored settings.

The primary beneficiaries are software engineers and tech job seekers who are facing grueling technical interviews, especially those who may be rusty or struggling with specific problem patterns. It's particularly useful for candidates aiming for top-tier companies where LeetCode performance is critical. The real-world use case is straightforward: you run Interview Solver discreetly during your interview, and when presented with a challenging problem, you use a hotkey to capture it and receive an AI-generated solution to guide your own coding, potentially turning a stumbling block into a confident pass.
